@meeseeksdev backport 1.1.x

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

$ git checkout 1.1.x
$ git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

$ git cherry-pick -m1 7e919373236a538b9157359af9c7b8ca3d32e920

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

$ git commit -am 'Backport PR #35794: BUG: issubclass check with dtype instead of type, closes GH#24883'

4. Push to a named branch :

git push YOURFORK 1.1.x:auto-backport-of-pr-35794-on-1.1.x

5. Create a PR against branch 1.1.x, I would have named this PR:

"Backport PR #35794 on branch 1.1.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!

If these instruction are inaccurate, feel free to suggest an improvement.
